Charles Ellicott Commentary Leviticus 7:29

"Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace-offerings unto Jehovah shall bring his oblation unto Jehovah out of the sacrifice of his peace-offerings:" — Leviticus 7:29 (ASV)

He who offers the sacrifice of his peace offerings. —That is, if his peace offering is one of the three aforementioned classes. (See Leviticus 7:11.)

Shall bring his oblation. —That is, those portions of the peace offering which the offerer devoted to the Lord and to the officiating priest.
